`Application filed September 17, 1915. Serial No. 51,244.

l To all wwym, t may concern.'

` pertains to make and use the same.

This inventionrelates to a post card dis play rack. y y

An object of the` invention residestln the provision of a device which may be suspended from a .suitable support and on which a plurality of post cards or snmlar articles may be arranged in sets so that the members of each set will be disposedin opposite inclined relation to the members of theother set whereby the Vsets willbe turned in opposite direction upon the rising of currents of air through them.

A further` object of the `invention resides in so constructing the device that a musical sound will be produced upon the rotation offthe members carryingthe post cards.`

A further object of the invention resides in so constructingthedevice that the sweep which causes the said musicalsound may be adjusted with relation to the sound producing members.

Withthese and other objects in View, such as will appear as my descriptionprogresses, my invention comprises the combmation and Y arrangement of parts as set forth in and falling within the `scope of the appended claims.

In the drawing: Figure 1 is an elevational view of my device; Fig. 2 isa vertical sec-` tional view; Fig. 3 is a plan view of the upper plate; Figmfl is a section on line LA of Fig. 1; Fig. 5 is an enlarged detail of the sweep; Fig. 6 isa section on line -6-6 of 45 ing the manner of securing the sections of Fig. 2; Fig. 7 is a` fragmental detail Showthe rim together; and Fig. 8` is a fragmental detail showing the post cardholder used with the device. f

Referring to the drawings by reference characters wherein like parts are indicated by like characters throughout the several views: In the embodiment of my invention shown in the drawing,` I have provided a plate 1 which has an outer row and an innerrow 3 'off perforations therein and a plurality Extend/ing through this plate l and through awasher 5 on the lower face thereof is a hook 6 by means of which the plate may be secured to a suitable support. An eye 7 is formed on the lower end of the said hook for a purpose which will later appear. Arranged through the perforations 2 and 3 are cords 8 which have eyes 9 on the ends thereof located beneath the plate 1. These cords may however be swung over the edge of the plate between the teeth 4L if desired. Detachably secured to the eyes 9 by means of hooks 10 and cords 11 are tone plates l2 which are arranged in spaced rows, one being beneath the row of holes 2 Aand the other beneath the row of holes 3. Secured to the eye 7 by means of a hook is a rod 13 which is provided with a hook on its lower end.` Engaged with this latter hook by means of an eye 14 is a rod 15, which rod has an eye 16V on its lower end. Secured to the lower end of the rod 15 is a casing 17 in which a plate 18 is mounted. This plate 18 is provided with a groove in which ball bearings of teeth 4 formed on its periphery.

191 are mounted. Resting on these ball bear 211to the upper face of the disk 23 through ahole in which the rod 15 extends which hole is. of less diameter than the hole through the disk and of slightly greater' diameter than the diameter of the rod. Thus when the disks swing slightly laterally the washer 24. will contact with the rod land the friction produced thereby will be slight. Thus it will be seen that the plate 20, the block 21 and the disks 2,2 and 23 form a rotary ele-` ment. which is supported by and rotates on the ball bearings mounted on the plate 18 which rod l5.

Extending radially from the upper face ofthe disk 22- are arms25 which are located in grooves formed by Vupwardly extending plates 26. The arms 25 are supported by plates25. Theinner ends of these arms 25- are upturned and these upturned ends plate 18 is held stationary with the are located in pockets 27 arranged around the peripheral face of the disk 23.. A band 28 encircles this disk 23 and maintains the upturned ends of the arms in their proper positions. The arms will thus be prevented from rotating. These arms are bent downwardly to form a horizontal portion having depressions 23 therein and thence upwardly to form fingers 29. Extending from one to the other et these fingers isa rim which is made up of a plurality of sections having overlapping flanges 30 with which clips 31 are engaged to maintain the sections together. These sections are also provided with loops 32 through which the iingers 29 pass. This rim is provided so that articles may be attached thereto for exhibition purposes. Extending from one to the other of the horizontal portions of the arms 25 are wire rings 33 which are located in the depressions 28 and have downwardly inclined loops 34 i'or the reception of the .post card holders later described. These post card holders which are used with my device consist of plates having a plurality of notches 35 in the edges thereofwhich plates may be slippedv between the sides of the loops 34 until the lower ends of the loops are located in the notches in the plates at which time the plates will be clamped in position and prevented from lateral movement. These plates are provided with clips 36 which extend outwardly from one face of each and which are adapted to engage and maintain a post card in place on the plate. lhen the plates are arranged in the loops 34r'and the post cards are on the plates they are mounted so that the post cards will be visible from beneath. The plates are also provided with lugs 37 which are adapted to engage over the upper edge of the rim so that the post cards may be displayed on the rim also.

Securedv to the eye 16 on the lower end of the rod 15 is a rod 38 on the lower end of which a casing 39 is secured in which casing a plate 40 is mounted. A plurality of ball bearings 41 are mounted on this plate 40 and support a plate 42 from the upper face of which a block 43 extends which is secured to the lower face of a disk 44. A similar but smaller disk 45 is secured to the upper face of the disk 44 and a washer 46 is provided to prevent the lateral movement of the disks 44 and 45 in the same manner as described in connection with the washer 24. Secured to and extending outwardly from the disk 44 are arms 47 which are secured to the disk in the same manner and by means similar to those described as securing the arms 25. These arms 47 are provided with depressions 48 in which rings 49 similar to the rings 33 are mounted. Thus it may be seen that the post card holders may be secured able burner may be placed beneath'the de-` vice so that the supply of currents of air thereto will be constant. r

In order that a series of sounds may be produced as the rotary elements move, I

have secured a rod 50 to the `disk 23 and have formed a Vloop 50 inthe same which is located within the disk and will prevent the turning of the rod. Rotatably mountedlon the outer end ot this rod 50 is a sweep which` consists of a pair .of plates disposed on opposite sides of the rod and secured together, between which plates a brush 51is mounted which is adapted to engagethe lower ends of the tone plates 12. The'fportion of this sweep which islocated below the rod 50 is of greater weight than the portion which is located above the rod so that the sweepis` normally held in a vertical position with the brush 51 extending upwardly. Rotatably mounted on the end of this rod 50 is a cylindrical member 52 aroundwhich a rubber band 53 extends which alsoiextends around a hook shaped portion 54 of the rod 50 so as to hold the cylindrical member 52l in any of its rotated positions. This cylindrical member is providedwith a connecting bar 55 which has a hook on` the end thereof extending through an aperture in the sweep. Thus when the member 52 is rotated in either direction the sweep will be swung from its vertical plane and the brush will be lowered or raised so thatk its engagement with the tone plates 12 will be varied and thus the volume of sound produced also varied.`

Thus it will be seen that I have provided a post card display rack which is of such construction that the post cards will be varranged in sets and the rising of currents of air through the sets will cause themj to turnv in opposite directions. Furthermore I have so constructed the device" that it will-be easy and inexpensive to manufacture .and successful in its operation.

TWhile I have illustrated and described a particular embodiment of my invention, it has merely been for the sake of convenience and I do not wish to be limited to that par ticular embodiment as it is obvious that numerous changes may be made within the scope of the appended claims. y

What I claim is z-A` 1. In a post card display rack, the combination with a vertically extending rodof a casing mounted on the rod and having a bearing plate therein,

with a disk, of a second disk of less diameter than the iirst mounted on the upper face of the first disk, pairs of spaced plates arranged on the upper face of the iirst mentioned disk Copies of this patent may be obtained for ve cents each,

and extendingradially from its periphery inwardly and terminating in spaced relation to the second mentioned disk, the said second mentioned disk having apertures in its 2G periphery arranged adjacent each pair of plates, arms extending between said plates and having upturned ends in said apertures and a band encircling the second mentioned disk and engaging the upturned ends of the arms.

In testimony whereof, I afiiX my signature, in the presence of two witnesses.
